    I have finally managed to write my conferencing/booking system, yet there's
    one niggling problem left, which I would like to get advice on.

    One part of the system works like this:

    There is a "video screen" object in the main room, which has messages on it.
    When a person books a room for a conference, a message is added to this
    object like this:

         #123.messages = listinsert( #123.messages, message )

    When a person unbooks a room, the message is removed.

    The problem is that I haven't yet touched the permissions on the "screen"
    object, and any character can just pick it up and walk away with it :)

    However, I'm afraid that if I change it, people won't be able to write to it
    from the "book" and "unbook" functions.

    I don't want to mess with this until I get advice, since I might create some
    permission loopholes.

    Hope somebody can suggest something...

    TIA.
